How to change the default package.json location in npm? - node.js

Question

I have a TestCafe test project.
This is the "scripts" portion of package.json:
"scripts": {
"test": "testcafe chrome tests"
}
When I try to run the npm script, this is what I get:
0 info it worked if it ends with ok
1 verbose cli [
1 verbose cli 'C:\\Program Files\\nodejs\\node.exe',
1 verbose cli 'C:\\Program Files\\nodejs\\node_modules\\npm\\bin\\npm-cli.js',
1 verbose cli 'run',
1 verbose cli 'test'
1 verbose cli ]
2 info using npm#6.13.1
3 info using node#v13.3.0
4 verbose stack Error: ENOENT: no such file or directory, open 'E:\package.json'
5 verbose cwd E:\
6 verbose Windows_NT 10.0.18362
7 verbose argv "C:\\Program Files\\nodejs\\node.exe" "C:\\Program Files\\nodejs\\node_modules\\npm\\bin\\npm-cli.js" "run" "test"
8 verbose node v13.3.0
9 verbose npm v6.13.1
10 error code ENOENT
11 error syscall open
12 error path E:\package.json
13 error errno -4058
14 error enoent ENOENT: no such file or directory, open 'E:\package.json'
15 error enoent This is related to npm not being able to find a file.
16 verbose exit [ -4058, true ]
So, it is complaining about not finding E:\package.json which is true, because my project is in E:\projectName\.
How can I tell the npm to look for package.json in E:\projectName\package.json? How come it is not searching for it inside the project folder by default?

Answer 1

You can use --prefix option.
In your case:
$ npm --prefix E:\projectName\ ...

Answer 2

This was my mistake.
I was starting the script with npm test instead of with npm run test. Now it is working.
